MACHINE FOR AFFIXING FASTENINGS TO ENVELOPES.

T 0 all whom it may concern:

Be it known that we, CLIrrroN R. SCUDDER and JAMES B. HUoUELnr, citizens of the United States of America, andresidents of St. Louis, Missouri, and Chicago, Cook County, Illinois, respectively, have invented a certain newand useful Improvement in Machines for Afiixing Fastenings to Envelopes, of which the following isa s'pecifi cation.

Our invention relates to .a machine for affixing fastenings to envelopes, and particularly to that type of machine in which the seal flap and body of the envelope are provided with a circular washer or disk attached thereto by eyelets to one of which a closing cord or string is attached with the free end adapted to be wound successively around the two eyelets and beneath the washers thereby securely uniting the seal flap and body of the envelope.

In machines of this character as heretofore constructed, it has been necessary to perform separate and distinct operations in. order to apply the fastening means to the seal fia and to the body of the envelope. The ob ect of our invention is toprovide a machine in which the fastening means may be applied to the body of the envelope at one and the same tirne that the fastening means is secured to the seal flap,'-these two fastening means being applied by a single operation of the machine.

our invention will be more readily understood by having reference to the accompanying drawings in which we have illustrated 7? of Fig. 6.

Fig. 10 is a view of an envelope after the attaching means have been. secured thereto I e p l Our machine (3011815115. essentially of an upright frame 20 having a forwardly extending supporting bed 21 which is formed with a pointed nose adapted to be inserted within the envelope 22 to which the fastening means are to be secure-d. As shown in Fig. 1, when theenvelope is in position, the seal flap is supported by the uplper surface of the supporting bed while tie forward edge of the body of the envelope is adjacent the lower surface of the projecting nose of this supporting bed. Mounted on the upper surfaceof the supporting bed is an anvil 23 co-operating with which there 'is suitable mechanism including a punch, eyelet feed, disk and string feeding mechanism for feeding and securing 'to the seal flap of the envelope the disk and. string attachilrlig t is mechanism, means for feeding and securing a reinforcing washer to the opposite surface of the seal flap.

Carried by the lower face of the projecting nose of the supporting bed 21 is an anvil 24 co-operating with which there is a plunger and-eyelet, disk, and reinforcing washer feeding means, somewhat similar to those per die except that the mechanism co-operating with the lower die has been modified and changed somewhat the first mechanism which operates down- '60 Fig. 11 is an enlarged cross sectional view gel- 31. While thel'diskfand eyelet a! be ng fed to the upp'erfsurface ,oflthe seal.

- ing link 49'and a cam- 50 on the shaft 26 so wardly against the upper surface of the supporting bed.

The mechanism'shown in association with the upper .anvil is of itself no part of our present invention, except in so far as this upper operating mechanism co-operates with the mechanism associated with the lower anvil in making a machine which operates to simultaneously and by one operation apply the fastening means to both the seal flap and the body of the envelope.

The power for driving the entire mechanism is derived from a driving pulley25, which is connected to the shaft 26 through a suitable one revolution clutch mechanism 27 indicated diagrammatically, which clutch can be of any well known type and is controlled by the footpedal 28 so that upon operating the same the shaft 26 is caused to makeone complete revolution, all in the manner well understood in connection with the operation of machines of this character. Connected to the driven member of. the clutch 27 is a crank arm 29, the upper end of which is connected to the rocking arm 30, the opposite end of which is connected to the reciprocating plunger 31, which plungcrcnrries at its lower end the yielding pin 32, whiclris adapted to engage with an eyelet in the eyelet-chute 33, to which eyelets are fed from a hopper 84 in the usual and well known manner. This eyelet-chute is pivotally mounted and adapted to be swung outoi' the way of the plunger as it descends-in the manner well understood in the art. Adjacent to the plunger 31 there is a stack of disks or washers 35 mounted upon a hollow rod 36 through which rod the string 37 is fed. At the bottom of this stack oi disks there is a reciprgwating slide 38 which is reciprocated through the medium of suitable connections from the cam 39. mounted on the shaft 26 engaging with which cam is a roller 40 carried by one end of the pivoted arm 41. (onnected with the opposite end oi this arm is nnupwardly extended arm 42, the upper .end of which is connected to arrank 43 on one end of a horizontal shaft 44. Secured to the opposite end of this shaft s an arm 45 connected to the slideythe armz io being provided with a handle vfor hand operation cated to feed the lowerd by the descending" pin32'carried by theplun flap, a reinforcingwasheiis being-"f fr the paper reel 46 into'p'osition we tothe opposite surfaceof this-flap.

connecting slide is provided with a shouider 68 so t yengaged' secured: 3 of paper 47 wound upon this 1reel; isfpassedf shaft a crank '72 is connected,- th'rough a pair of feedjrollers {L8qwliicliarei .lug 73 on the slide 6'4". This one is such that as the cam 39 rotates,

As this paper is fed forward, it passes be tween a pair or". clamping members 51-52 provided with cutting edges which engage with a cutting member 3i punch 54. is likewise supported beneath the clamping members 51-1-52, and is adapted to pass through openings in these members. These 'clamping members are carriedon the ion ward end of a pivoted member 55, the rear end of which is connected to a connecting link 56 and is adapted to be reciprocated through the operation of a cam mounted upon the shaft 26 so that as the paper is fed forwardly over the anvil 23, the arm is rocked so as to move the cutting edges of the clamping members Si-52 downward against the cutter 53, thus cutting on? a section or the paper so as to form a reinforcing washer. At the same time the punch punches a hole in the section of the paper to be used as the next succeeding reinforcing washer.

The mechanism for applying the fasteninn" means to the body of the envelope and which co-operates with the anvii 2 2 on the under face of the supporting hcdi with which mechanism our invention is chiefly concerned, consists as heretofore stated oi elements somewhat similar to those already described in connection with the mechanism co-operating with the upper anvil. There is provided a reciprocatingpln'nger 5? which carries a spring-pressed pin 5th which plunger. is adapted to be reciprocated through the medium oi. the crank iii) and links eooi. Jr stack of washers or disks (52 are mounted upon a rod 63, but instead of being fed by gravity, as in the case of the upper washera it' is necessary to provide a positive means for feeding these disks upwardly on this red. This is accomplished by means of acarriagre (Sal which engages the lowermost disks and is forced upwardly by power derived from the'wcight G5 which is connected to this carriage through the medium oi. a rope '56.

In this manner there is constant upward Mid llltl reciprocating slide 6?; (See Fig. 7. This .i-j

This slide is adapted .tohe'reciprocated by the operation the cam 39 mounted on the shaft 25 rocking armfil to ithe outer end of w A the arm 69 is secureoh. the upper end oi? arm being: secured to a crank Y0 on one end o'f'a shaft-71. To theopp'osite 3end of end of which is connected to;

6? is reciprocated so as to feed the top" waslier and feeds the same atera yso that this supporting disk or washer in the stack 62 forwardly plunger 57. In order to properly support the washer. when it is thus fed off the top of thestack, it is necessary to provide spe-- v nections 98-99, which are connected to the cial supporting means such as are shown in detail'in Figs. 5 to Sg/Tliis consists es-.

sentially of a supporting memberm mounted upon the slide 67, which" s upoprting member is provided with a forwardly extending portion having a pair of downwardly curved supporting arms 76 which are in a position to receive and hold thewasher. The end of the supporting member 74 is cut away at 77 to permit the yielding pin 58 to engage'with a washer supported by the slide. This supporting slide 7% is connected to the main slide 67 by a spring connection 78 and the main slide 67 is -provided with an upwardly projecting portion 79 which, upon the forward movement of the slide 67, is adapted to engage the forward end of the supporting slide 7 4 and force the same outwardly into the position shown in Fig. 5. That is, in operation the slide 1s normally in the position shown in Figs. 6 and 7, but as the slide 67 is forced outwardly it picks the disk off the top of the stack and moves the same on to the supporting arms 76 and then the slide 67 and supporting members 74 move together until this disk is carried into a position immediately over the spring-pressed 'pin 58. Then as this pin moves upwardly, the washer is slipped over the end of the pin and then the slide 67 is retracted and the spring 78 pulls the supporting member 74 backwardly member is moved out of the path of the-reciprocating plunger 57. The eyelets for the lower fastening means are supplied from a suitable hopper 80 down the eyelet-chute 81, which eyelet chute is carried by a sliding member 82 which is adapted to be reciprocated through the medium of the link 83, the opposite end of which is connected to the arm 84:, upon one ing rollers 87-88, which are rotated so as to advance thepaper step by step through the medium of the pawl and ratchet connections 89 and 90 controlled by the arm 91, the opposite end of which arm is connected to the pivoted lever 92 which in turn is connected to the arm 4.9 operated by the cam 50. The paper is fed between the two clamping jaws fi5 93-94 which jaws are provided with out ting edges co-operating with the cutter 95.

'A punch 96is adapted to pass through openings in these two clamping members, which clampingmembers are carried on the forward end of a pivoted arm 97 and is adapted to be rocked through the medium of the conreciprocating rod 56 which controls the upper cutting m'echanismheretofore described. With this construction,it will be seen that as, the clutch is operated by the foot-pedal fastening means are thus appliedto the flap of the envelope, the reciprocating slide 67' is operated to feed adisk off the top of the lower stack onto the supporting fingers 76,

which supporting fingers are then moved forwardly with the slide to a position over the spring-pressed finger 58 of the reciprocating plunger 57. As this plunger is moved upwardly, it first picks off an eyelet from out of the path of the plunger, and thenthe spring-pressed finger passes through the opening in the diskor washer held by the supporting finger 76, which supporting fingers are then withdrawn with the slide 67,

the chute, which chute is then reciprocated and then the plunger continues into engagement with the anvil 24 to thereby upset the eyelet and securing the disk or washerto the body of the envelope. At the same time the paper strip 86 has been fed forwardly and cut off by the cutter 95, so that a reinforcing washer is secured to the inner surface of the envelope.

It will thus be seen that we have devised a very efficient machine in which the attaching means can be applied simultaneously to the seal flap of the envelope and to the body of the envelope by asingle operation of the machine, and while we have described one spccificembodiment of our invention, it will be understood th at we do notwish to be 1im ited to the exact construction shown and de scribed, but that various changes and modifications may be made without departing from the spirit and intent of our invention.

What we claim as our invention is:

-1. In a machine of the class described, eyelet setting means for securing a circular disk or washer to the body portion of an envelope, aiid a second eyelet setting means for simultaneously securing a circular disk or washer to the seal flap of the envelope.
